Bad services

telkom debited my account in 2018 in august before my pay date on the 25 of each month, there was a fee that i was which is R 201 for a debit order that bounced, what i need to understand is whose fault it is that they went into my account before my pay date? who is responsible for that R201 charge? i have been dealing with this company about the same thing ever since August last year and no one is able to sort this out for me. now my account shows that it is in arrears because of this R 201 which i am not responsible for. i have been trying to speak to a team leader since this incident and not even once have i spoken to team leader because they are always "busy" for some reason. this is creating a bad name for my credit rating and someone needs to sort this out! i have sent through all the proof required to Elridge Rihlampfu which is the agent that assisted me on the 05/04/2019 and the case number provided was ********** 8. if this does not get sorted out the clearly my lawyers will have to intervene , i will not be dealing with this company about the same damn query for 8 months and still cant be sorted out. this is disgusting customer service especially for a big telecommunication company like this .
